What the insurance companies are looking for is an objective statement that you have a deviated septum and not just looking to get a rhinoplasty. A CT report does just that. MRI is not as accurate or specific for septal anatomy. If the septum is fairly crooked, some will accept photos taken of the inside of your nose with an endoscopic camera.
Is It Necessary to Have a Ct Scan for Septoplasty? Will Health Ins. Still Pay if I Do Not Have the Scan Done? Can an MRI Be Used
